Welcome to Math-Logger: Your Go-To JavaScript Library for Mathematical Logging and Debugging

Math-Logger is a powerful JavaScript library designed to assist developers in logging and debugging mathematical operations in their code. Whether you are working on complex mathematical computations or just simple arithmetic, Math-Logger provides a robust set of APIs to enhance your debugging experience.

Getting Started with Math-Logger

First, you need to install Math-Logger using npm:

  
    npm install math-logger
  

API Overview and Examples

1. Basic Logging Functions

The basic logging functions include logging the result of operations and intermediary steps.

  
    const mathLogger = require('math-logger');

    mathLogger.logAddition(5, 3); // Logs: 5 + 3 = 8
    mathLogger.logSubtraction(7, 2); // Logs: 7 - 2 = 5
    mathLogger.logMultiplication(4, 6); // Logs: 4 * 6 = 24
    mathLogger.logDivision(10, 2); // Logs: 10 / 2 = 5
  

2. Advanced Mathematical Operations

Math-Logger also covers a variety of advanced mathematical operations including power, square roots, and factorials.

  
    mathLogger.logPower(2, 3); // Logs: 2^3 = 8
    mathLogger.logSquareRoot(16); // Logs: sqrt(16) = 4
    mathLogger.logFactorial(5); // Logs: 5! = 120
  

3. Trigonometric Functions

Logging trigonometric functions can be very useful in debugging graphical applications and simulations.

  
    mathLogger.logSine(Math.PI / 2); // Logs: sin(π/2) = 1
    mathLogger.logCosine(Math.PI); // Logs: cos(π) = -1
    mathLogger.logTangent(Math.PI / 4); // Logs: tan(π/4) = 1
  

4. Custom Logging Function

For more complex calculations, you can create custom logging functions:

  
    function complexCalculation(a, b, c) {
      let result = (a + b) * c;
      mathLogger.customLog(`(${a} + ${b}) * ${c} = ${result}`);
      return result;
    }

    complexCalculation(2, 3, 4); // Logs: (2 + 3) * 4 = 20
  

App Example: A Simple Calculator using Math-Logger

Let’s create a simple app that utilizes the Math-Logger APIs to perform and log various calculations.

  
    const express = require('express');
    const mathLogger = require('math-logger');
    const app = express();

    app.get('/add/:a/:b', (req, res) => {
      let a = parseFloat(req.params.a);
      let b = parseFloat(req.params.b);
      let sum = a + b;
      mathLogger.logAddition(a, b);
      res.send(`Sum: ${sum}`);
    });

    app.get('/subtract/:a/:b', (req, res) => {
      let a = parseFloat(req.params.a);
      let b = parseFloat(req.params.b);
      let difference = a - b;
      mathLogger.logSubtraction(a, b);
      res.send(`Difference: ${difference}`);
    });

    app.get('/multiply/:a/:b', (req, res) => {
      let a = parseFloat(req.params.a);
      let b = parseFloat(req.params.b);
      let product = a * b;
      mathLogger.logMultiplication(a, b);
      res.send(`Product: ${product}`);
    });

    app.get('/divide/:a/:b', (req, res) => {
      let a = parseFloat(req.params.a);
      let b = parseFloat(req.params.b);
      let quotient = a / b;
      mathLogger.logDivision(a, b);
      res.send(`Quotient: ${quotient}`);
    });

    app.listen(3000, () => {
      console.log('Server running on port 3000');
    });
  

With these examples and the simple app, you can see how Math-Logger simplifies the process of logging and debugging mathematical operations in JavaScript. Happy coding!
